Protection Functions
Motor Protection Motor overheat protection via output current sensor
Overcurrent Protection Drives stops when output exceeds 200% of the rated current (Heavy Duty)
Overload Protection
A stop command will be entered after operating at 150% for 60 s (Heavy Duty)
<3>
Low Voltage Protection
Drive stops when DC bus voltage falls below the levels indicated:
190 V (3-phase 200 V), 160 V (single-phase 200 V), 380 V (3-phase 400 V), 350
V (3-phase 380 V)

Braking Resistor Overheat Protection Overheat input signal for braking resistor (Optional ERF-type, 3% ED)
Stall Prevention
During acceleration and during run: Separate settings for each type of stall
prevention determine the current level at which stall prevention is triggered.
During deceleration: Select, enable/disable.
Cooling Fan Failure Protection Circuit protection (“fan-lock” sensor)
Ground Protection
Electronic circuit protection
<4>
DC Bus Charge LED Remains lit until DC bus voltage falls below 50 V
